shell layer system, methods for surface preparation of various composite substrates and for forming a bonded composite structure

摘要

1/1 summary “shell layer system, methods for surface preparation of various composite substrates and for forming a bonded composite structure” a rich shell layer in resin (11) that leaves no residual fibers behind detachment and can work well with different resin-based composite substrates (10). The resin rich shell layer (11) is composed of a woven cloth (11b) impregnated with a resin matrix (11a) different from the resin matrix of the composite substrate (10). the shell layer (11) is designed such that after manual removal of the shell layer (11) from the surface of the composite substrate (10), a thin film of the shell layer resin remains in the shell. surface of the composite substrate to create a bondable surface capable of bonding with another composite substrate (12), however no fibrous material of the woven cloth remains on the same surface.
